PAUL K. BARKER, OF GREER, SOUTH. CAROLINA.

MACHINE FOR STRAIGI-ITENING SPINDLES.

Specification of Letters Patent.

' Patented ma 4, 1916.

Application filed June 10, 1915. Serial No. 33,343.

To all whom it may concern Be it known that I, PAUL K. BARKER, a citizen of the United States, residing at Greer, in the county of Greenville and State of South Carolina, have invented certain new and usefulImprovements in Machines for Straightening Spindles; and I do' declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in apparatus for determining and straightening uneven features of spindles and more particularly to cotton mill spindle straightening machines.

The object of the invention is to provide a simply constructed and efficient machine of this character in which the uneven or bent portions of a spindle may be quickly detected and remedied.

With this and other objects in view, the

invention consists of certain novel features of construction, and the cornblnation and arrangement of parts as Wlll be hereinafter described and claimed.

In the accompanying drawings: Figure 1 represents a plan view of a machine constructed in accordance with this invention; Fig. 2 is a side elevation thereof; Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1; Fig. 4: is a similar view taken on the line of Fig. I; Fig. 5 is a similar view taken on the line 5-5 of Fig. 1.

In the embodiment illustrated an anvil 1 is shown mounted on a bed plate 2, which latter is supported on suitable legs 3. Projecting upwardly from the anvil 1 are two longitudinally spaced standards 4: and 5, one of which has a threaded bore 6 extending therethrough in a plane parallel with the longitudinal axis of the machine and the other is provided in its upper end with a V-shaped notch 7 designed to receive one end of a spindle S. Another standard 8 rises from the bed plate 2 at any suitable point, being here shown positioned about midway the length of said bed plate and which has its upper end disposed in longitudinal alinement with the upper notched end of the standard 4 and is similarly notched as shown at 9 to receive and assist in supporting said spindle S.

The anvil 1 is shown provided in one side thereof with a plurality of openings 1 which increase gradually in size from one end to the other of the series and which are designed for a purpose hereinafter to be described.

A bar 10 is supported at one side of the supportmg standards 4 and 8 adjacent thereto and is mounted for vertical adjustment in the standard 5 and in the standard 1l which rises from the body plate 2, at a point beyond the standard 8. The bar 10 is provided with transversely extending arms 10 at its opposite ends which are longitudinally slotted as shown at 10 and through which extend mounted set screws 12 which are connected with the standards 5 and 11, and by means of which said bar is adjusted vertically in the slots 10 of the bar..

A detector for finding defects in a spindle is adjustably mounted on the bar 10 and 4 15 and said point is designed to engage the spindle under treatment for determining any unevenness or bonds therein, the spindle being turned in its supports for the purpose of subjecting all parts thereof to the action of said detector.

The outer end of the screw 13 is provided with a milled head 16 for turning the screwto adjust it relative to the spindle. The bracket 1% which carries the screw 13 is mounted for longitudinal adjustment on the bar 10 and is adapted to be held in adjusted position by means of a set screw 17 which clamps said bracket in adjusted position on the bar, thus securely holding it relative to the spindle on which the screw or detector 13 is designed to operate.

A screw 18 is here shown adjustably mounted in the bore 6 of the standard 5 and is provided at its inner end with a socket 19 which is designed to receive one end of the spindle S to assist in supporting said spindle and which is designed for moving it longitudinally in the notches 7 and 9 in which it is mounted. This screw 18 is provided with an actuating milled disk or head 20 by means of which the screw'is turned for reciprocating it longitudinally relative to the detector.

In the use of this machine, a spindle S is first inserted in the notches 7 and 9 of the standards 4 and 8 with one end thereof engaged with the socket 19 of the screw 18. When it is so positioned the detector 13 is adjusted relatively to the spindle by the means above described, and when it is set, said spindle is turned to subject all parts of the periphery thereof to the detector, and after the bent portion or defect therein has been determined then the spindle is placed on the anvil 1 and hit with a hammer for straightening it. After the spindle has been straightened, if desired one end of the spindle may be inserted in one of the openings 1 of the anvil and there held until it is desired to remove it for other purposes.

I claim as my invention 1. In an apparatus for detecting portions of a spindle which are out of alinement, the combination of a supporting structure, spindle supports rising therefrom, a bar disposed in a plane parallel with and at one side of said spindle supports, said bar and supporting structure having cooperating means for permitting the vertical adjustment of the bar, a bracket adjustable longitudinally on said bar, and a detector carried by said bracket and adjustable longitudinally therein.

2. An apparatus for detecting portions of a spindle which are out of alinement comprising a supporting structure, spindle supports rising therefrom, a vertically adjustable bar disposed in a plane parallel with and at one side of said spindle supports, a bracket adjustable longitudinally on said bar, and a detector carried by said bracket and adjustable longitudinally therein and laterally relative to the spindle to be tested, said detector being in the form of a screw mounted in a threaded opening in said bracket and having a point for engagement with the spindle to be tested.

3. An apparatus for determining portions of a spindle which are out of alinement comprising a supporting base, standards rising therefrom and provided in their free ends with notches designed to receive a spindle to be tested, other standards rising from said 5 base and having laterally extending set screws, a bar having slots adjustably engaged with said set screws, said bar being arranged at one side of the plane occupied by said first mentioned standards, a 5 bracket adjustably mounted on said. bar and having an upwardly extending arm provided with a threaded aperture, and a screw mounted in said aperture and adjustable toward and away from the plane occupied by 6 the upper ends of said first mentioned standards.

4:. An apparatus for detecting portions of a spindle which are out of alinement comprising a supporting structure, spindle 6 supports rising therefrom, a bar mounted for vertical adjustment and disposed in a. plane parallel with and at one side of said spindle supports, a bracket adjustable longitudinally on said bar, and a detector carried 7 by said bracket and adjustable longitudinally therein and laterally relative to the spindle to be tested, said detector being in the form of a screw mounted in a threaded opening in said bracket and having a point '7 for engagement with the spindle to be tested, a standard rising from said supporting structure and having a threaded aperture extending therethrough, and a screw mounted in said aperture and having a socket at its in- 8 ner end positioned for receiving one end of the spindle.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
